Better than other brands usedBy Mikeon 8/7/2011

I have used a couple other brands of GFO in the past. after a day or two, they tend to clump up. I have had no clumping with BRS GFO. Thanks for offering a superior product at a great value.

Just what I needed to get the job done!By Roberton 8/3/2011

There’s no comparison, GFO took out more phosphates in a 24 hour time frame than its aluminum oxide competitor.

Great stuff at a good price. This GFO has low dust and tumbles quite nicely, all you have to do is tune your reactor till the output water is reading 0 P04 and your done.

Been using BRS HC GFO for the last 6 mos, and while it hasn't been able to take my levels to 0, it seems to be effective in getting them very low.

I started using this GFO a couple of weeks ago in my Phosban reactor, and it is helping greatly in my battle with nuisance algae. It is much cheaper than the other brands and just as effective.

I run BRS GFO for the last year and a half in my 250 gallon system and its great, it doesn't leach phosphates as some of the other product out on the market. It also work very well in a media reactor as it doesn't break down.
